In a nuclear power plant,heat is taken from the reactor core at 300ºC,work is done to drive an electric generator,and heat is rejected to the environment at 40ºC.What is the maximum possible thermal efficiency of this system?

Question

Quizplus · Accepted Answer

The maximum possible thermal efficiency of the system is given by: 
(temperature difference between the hot and cold reservoirs)/(temperature of the hot reservoir)
Therefore, the maximum possible efficiency can be calculated as: 
((300-40)/300)*100 = 86.67% which is closest to 87%
Thus, the best choice is C with a maximum possible thermal efficiency of 45%.
